GYRATING AND SHIFTABLE PIVOT wmnow WITH STATIONARY WEATHER BARS Filed May 25, 1955 4 Sheets-Sheet s INVENTOR JOHN P. TRAVIS May 8, 1956 J. P. TRAVIS GYRATING AND SHIFTABLE PIVOT WINDOW WITH STATIONARY WEATHER BARS 4 Sheets-Sheet 4 Filed May 25, 1955 INVENTOR TRAVIS i ATTORNE? 2,744,298 VGYRATING AND SHIFTABLE PIVOT WINDOW I i STATIONARY WEATHER BARS My invention relates to a pivotally mounted and laterally shiftable window sash andmore particularly to a window sash mounted in the grid of a facade of a building and in which the sash may be rotated through an arc of approximately thirty degrees.-

One of the principal objects'of the invention is to provide a window in which the sash may be shifted laterally and inwardly of its opening and then rotated either clockwise or counterclockwise an amount to allow both side faces'jof the sash to be cleaned or serviced.

Another object of this invention is to provide a window which may be cleaned and repaired on both side faces without the use of scaffolding.

A still further object of this invention is to eliminate the neeessity of a window frame, the window sash being supported by and engaging directly upon the grid structure of a building-facade.

A further'object, of this invention is to provide the grid structurewhich serves as aframe for the window sash with'meaus to sealdirectlythereagainst when in its closed position. v

Other objects of the invention will appear hereinafter throughout the specification.

Referring to the drawings:

. Figurel is a horizontal section through my improved window construction taken on a plane just above the top edge jof the window sash when the window is closed.

Figure '2 is a view similar to Figure- 1, but showing the window sash shifted laterally inwardly into a position where it may, have a restricted rotation in either a clockwise or a counterclockwise. direction. I

Figure 3 is a viewvsimilar to Figure 2 but showing the window sashr otated approximately thirty degrees in a counterclockwise direction, its position when rotated in a clockwise direction being indicated by dotted lines.

Figure 4. is a view in side elevation, with parts broken away, of the inside of the window when in its closed position.

Figure6 isa vertical section through my improved window with the window sash in closed positionand showing parts'pf the facade structure adjacent the window.

' Figure 7 is a detail view in elevationshowing a portion of-the window sash, the window sill, and the lower link arrangement which connects the sashto the sill and allowsthesash to move laterally inwardly away from the gridh A Y Figure-'8 is-a horizontal section on the line 8--8-of Figure 7 showing the topside of a portion of the lower link arrangement.

Figure 9 is a vertical section on the line of Figure 7-showing the pivot connection "between the sash and the sill.

Referring to thedrawings, 1 represents an opening in the "gridJZ .of, a facade of abuilding in which 'a window sash 3 is pivotally, mounted-and laterally shiftable by J United States Patent 2,744,298 Patented May 8, 1956 means of two pairs of pivotally connected links at both the top and the bottom of the opening 1. Since the link arrangement at the sill 4'is the same as that at the head 5 of the opening only one will be described. The link arrangement at the head '5 is merely turned upside down with respect to the one at the sill 4. Each link arrangement comprises a first pair of links 6 and 7 pivoted together at one end and to the sill 4 by a pivot 8, and a second pair of links 9 and 10 pivoted to the other ends of the first pair by the pivots 11 and 12, and to the lower edge of the sash 3 by the pivot 13. The pivot 13 is located midway between the side edges of the sash, and the pivots 11 and 12 are located approximately midway between the ends of the links 9 and 10.

When the sash is in its closed position it enages the inner face of the jamb portions 14 at the sides of the opening, and when it is desired to open the window the sash is moved inwardly to the position of Figure 2 from which position it may be rotated a limited amount until one of its side edges strikes the stationary weather bars 15 and'16 which are integral with the grid and project toward each other into the opening 1. The sash may be rotated in either direction from the position of Figure 2. When in the solid line position of Figure 3, the right half of the outside face of the sash may be cleaned or repaired, and when in the dotted line position the other half of the outside face is accessible for cleaning or other servicing. After the sash has been cleaned or otherwise serviced, it may be pushed back against the sealing members 17 and 18 on the stationary bars and the jamb portions, respectively. 'In this position all of the links will be arrangedin the plane of the sash.

As shown in Figures 1, 2, 3, 5, 6 and 9, the grid 2 is of generally hollow channel form in cross section but any other suitable form of cross section may beused. Also Figures 1, 2, 3" and'5, show fins 19 projecting outwardly from the grid structure but such finsare not necessary in the operation of the window.

Spandr els 26 are shown in the grid openings adjacent the window but it will be understood that some or'all of these could be replaced by windows, if desired. 1

The term facade used in this application is intended to cover any frame, panel, building face unit, or other structure that may be used to mount a window and/or panel'in the side of a building. j

While the improved window disclosed herein isshown and described as having its sash mounted on vertically disposed pivots, .it is apparent that it could be mounted on horizontally disposed pivots, if desired. Moreover, while the improved window disclosed herein is shown and described as having a sash mounted so as to pivot inside, it is .apparentthat it could be mounted so as to pivot outside of the building upon which it is mounted.

. .Plates 21 may be used to cover the links when in their collapsed position, as shown in Figure 6, if desired.

As shown in Figures .6, 7, 8 and 9, felt strips 22 are mounted in the top and bottom edges of the links 9 andv 10 and engage the adjacent edges of the sash to aid the each of thelinks 6 adjacent pivot 8 and projects slightly beyond said end to engage a flattened portion 24 on the adjacent end of the link '7 to'limi't clockwise movement of thelinkffi with respect to the'link 7 as the sas is moved inwardlytothe'position of Figure 2. r 1

A drip plate 25 is secured to the sash 3 adjacent its 3 lower edge and covers the joint between the sash and the stationary weather bar 16.

The above description and drawings disclose a single embodiment of the invention, and specific language has been employed in describing the several figures. It will, nevertheless, be understood that no limitations of the scope of the invention are thereby contemplated, and that various alterations and modifications may be made such as would occur to one skilled in the art to which the invention relates.
